Hi. I had a *little* problem in my SCSI devices that halted my 4.0-stable box today. The console messages follows: (da1:ahc0:0:12:0): SCB 0x3b - timed out in Data-out phase, SEQADDR == 0x115 (da1:ahc0:0:12:0): BDR message in message buffer (da1:ahc0:0:12:0): SCB 0x47 - timed out in Data-out phase, SEQADDR == 0x115 These messages were in highlight, so I think they're important messages :). The SCSI devices of the box follows: ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xb800-0xb8ff mem 0xe2000000-0xe2000fff irq 5 at device 13.0 on pci0 ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs Waiting 15 seconds for SCSI devices to settle Mounting root from ufs:/dev/da0s1a da1 at ahc0 bus 0 target 12 lun 0 da1: <QUANTUM ATLAS IV 9 WLS 0909> Fixed Direct Access SCSI-3 device da1: 40.000MB/s transfers (20.000MHz, offset 8, 16bit), Tagged Queueing Enabled da1: 8761MB (17942584 512 byte sectors: 255H 63S/T 1116C) da0 at ahc0 bus 0 target 6 lun 0 da0: <QUANTUM FIREBALL ST4.3S 0F0C> Fixed Direct Access SCSI-2 device da0: 20.000MB/s transfers (20.000MHz, offset 15), Tagged Queueing Enabled da0: 4136MB (8471232 512 byte sectors: 255H 63S/T 527C) I also have a Sony DDS3 external tape drive, which is off at the moment. Sometimes when I connect the tape to system some strange SCSi errors appear in the console (I don't have any know, the tape was off in this boot...). What I'd like to know is what these error messages mean. I don't know much about SCSI. A month ago this machine lost a disk (which I changed). The two disks (da1 and da0) are in different SCSI channels (as you can see in the informations above). Am I playing dumb and there something I should do to not happen these errors. Or there is some evil in my hardware? Maybe there is some evil Spirit of Bytes who is playing with my machine (then I should call some kind of hardware exorcist). Thanks for your help. MaurícioWP.
